To aZZ whom it may concern.-

Be it known that I, HERMAN C. F. E. SNOW- MAN, a citizen of the UnitedStates, residing at New Paltz, in the county of Ulster and State of NewYork, have inventedcertain new and useful Improvements in Means forTransmitting Motion, of which the following is a specification.

My invention has relation to improvments in engines for transmitting orconverting energy for the actuation of machinery, and in such connectionit relates more particularly to means employed to transmit the forcegenerated by the engine to a transmitting shaft thereof.

My invention stated in general terms coinprises an engine constructedand arranged for operation in substantially the manner hereinafterdescribed and claimed.

The nature and scope of my invention will be more fully understood fromthe following description taken in connection with the accompanyingdrawings forming part hereof, and in which- Figure 1, is a side view inelevation of the transmitting mechanism embodying features of myinvention. Fig. 2, is a top or plan view thereof; and Fig. 3, is a viewpartly in side elevation and partly in section of the pawl pivotallyconnected with a fulcrumed leverarm operated by a crank in the mannershown in Figs. 1 and 2, and also showing the lug or step projecting froma sprocket chain adapted to engage with and to be disengaged from saidpawl.

Referring to the drawings A, is a stationary engine, comprising a pistoncylinder or barrel a, with a steam chest a, governor a a steam inletpipe a a piston-rod a provided with a slider (1 a connecting rod o inpivotal connection with the slider a and a crank a mounted on the end ofa transverse shaft B, which is journaled in standards I) and b, asclearly illustrated in Fig. 2.

On the shaft B, are secured a fiy-wheel B, and a pulley B, which latteris rigidly secured thereto.

0 and C, as fully shown in Fig. 2, are standards. C is a shaft journaledthereinandpro- Vided with a double face loose pulley c.

c, is a belt passing around the fixed pulley B and the loose pulley 0,0fthe shaft 0 The shaft 0 carries a V-shaped traveler 0 which is keyedthereto and which traveler c revolves the said shaft. Concentric withthe shaft '0 is a large stationary gear wheel D, which is provided withsupports d and 01', secured to the foundation or floor and adapted tomaintain the stationary gear-wool D, in such position as to permit ofthe rotation around the periphery of the same of a traveler gear E,which is mounted on the shaft 6, loosely heldtoposition in the outer endof the V-shaped traveler c The shaft 2, carries a pulley e, which isrigidly secured thereto and passing around this pulley e and the pulleyc, is a belt 6 On the shaft 0 is mounted a fly-wheel G On each end ofthis shaft C are applied and secured cranks d and The crank d, is pro-Vided with a stud-pin d engaging one end of a connecting rod d which atits opposite end engages the stud-pin d of the crank d, applied to theend of a shaft f, which is journaled in the standards 0 and O.

The transmitting shaft f, carries a pulley f, and surrounding the sameis abelt f connected with a pulley mounted on a shaft, not shown, butadapted to have motion imparted thereto by means of the beltf to apulley mounted 'on said shaft. The transmitting shaft f, is extendedbeyond the standard 0, and is journaled at its outer end in a standardg, as fully illustratedin Fig. 2.

On the extension f, of the transmitting shaft f, are securedsprocket-wheels h, and to a shaft 2', located at the base of thestandard O, are mounted sprocket-wheelsj. These sprocket Wheels areengaged by sprocket chains Z and Z, provided with projections or steps mand m, as fully illustrated in Figs. 1 and 2, for a purpose to bepresently more fully explained.

On the end of the shaft O providedv with the crank d havinga stud-pin (1is attached 9 5 thereto a slotted lever-arm d, and this leverarm d", isfulcrumed at (W, to the standard O, and at its forward end it isbifurcated and has pivoted thereto in any preferred manner a latch orpawl d, which is adapted to engage and disengage the steps orprojections 'm and m, of the sprocket chains Z and Z, so as to lift inone movement of the motor the sprocket chains in engagement with thesprocket wheels to energize the transmitting shaft f. This pawl d isarranged so that in the travel of the respective chains Z and Z, one ofthe steps on and m, thereof at a time will be brought into engagementtherewith by one movement of the slotted arm (1, as illustrated in Fig.1, and will then disengage the same when the lever arm (1, has assumedby the movement of the crank d, the position illustrated in full linesin Fig. 3, and with the pawl in such position as to again engage one ofthe steps or projections when the lever arm at, has assumed the positionillustrated in dotted lines in Fig. 3.

The operation of the motor hereinbefore described, is as follows:--Steamor other elastic fluid is introduced into the cylinder a, of the engineA, through the controlled inlet pipe a whereby the piston is set inmotion, and thereby through the connecting rod a, and crank M, to impartmotion to the transverse shaft 13, counter-balanced in the speed ofrotation thereof, by means of the fly-wheel B. The motion imparteddirectly by the piston to the shaft 13, is communicated by means of thepulley 13 through a belt 0, to the pulley c, and in turn from the pulleya, through a belt 8 to a pulley e, in order to actuate the traveler gearE, meshing with the large stationary gear-wheel D, and thereby travelingaround the periphery of said wheel D, and which traveler gear alsoimparts motion to the shaft 0 controlling the movements of the cranks d,d and d connecting rod d", slotted lever arm d, with its pawl (1 and incon: junction with the sprocket mechanism hereinbefore described and asfullyillustrated in 'Fig. 1, to impart motion to the transmittingtraveler arm, a gear E fixed on one end of the shaft 6, and adapted torevolve around the periphery of the stationary gear wheel D, a pulley e,keyed to the other end of the shaft e, a double face pulley c, looselymounted on the shaft (3*, a belt connecting the pulley B with saidpulley c, and a belt connecting said pulley c, with the pulley e, cranksd and d secured on the ends of the shaft 0 a transmitting shaftf, acrank 0Z on one end of said transmitting shaft, a rod (1 connecting thecrank d with the crank d, a slotted arm d, having the crank d, engagingin said slot, a pawl 0P pivotally connected to the end of said arm,sprocket wheels j, mounted on the shaft 1', attached to the standard C,sprocket-wheels h, keyed to the transmitting shaft f, chains Z and Z,connecting said sprockets and steps m and m, carried by said chains,substantially as and for the purposes set forth.

2. An engine provided with a shaft B, carrying a fiy-wheel B, a pulley Bmounted on said shaft, a stationary gear D, a shaft (3 a traveler arm 0secured to the shaft 0 a shaft 6 journaled in said traveler arm, a gearE,fixed on one end of the shaft e, and adapted to revolve around theperiphery of the stationary gear D, a pulley e, keyed to the other endof the shaft 6, a double face pulley c, loosely mounted on the shaft 0 abelt connecting the pulley B with said pulley c, and a belt connectingsaid pulley c, with the pulley e, a fly wheel 0, mounted on the shaft 0cranks (Z and d secured to the ends of the shaft 0 a transmitting shaftf, a crank d", on one end of said transmitting shaft, a rod (1connecting the crank (i with the crank d, a slotted arm (Z having thecrank d engaging in said slot, a pawl (Z pivotally connected to the endof said arm, sprocket wheels 3', mounted on the shaft t, attached to thestandard 0, sprocket wheels h, keyed to the transmitting shaft f, andchains Z and Z, connecting said sprockets and steps or projections m andm, carried by said chains, substantially as and for the purposes setforth.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
